In alpha decay the parent element and the daughter element can be different isotopes of the same element but in beta decay the parent and daughter element are always the same?

No. In both the cases the element would definitely change. As alpha particle comes out then the new element would have two less in atomic number where as in beta particle decay the new element will have one higher in atomic number.

When two atoms have the same number of protons but a different number of neutrons what are these atoms?
They are isotopes of each other.
Do isotopes of the same element have different atomic numbers?
NO. An element always has its own unique atomic number, because the atoms of that element all have identical amounts of protons. Counting the number of protons in a nucleus of an atom reveals the identity of the atom. So, all atoms of the same element have the same atomic number.However atoms of one element CAN have a different masscaused by different number of neutrons in nucleus: these are called isotopes of that element.No. The only thing that can change within an given element, is the atomic mass usually referred to as isotopes, which means there is a different abundance of each isotope.For example chlorine has two isotopes one which is 75.78% and a atomic mass of 34.969 and the second is 24.22% and a atomic mass of 36.966.Now calculate the average atomic mass and you have a answer of 35.45.
What part of an element is the same?
I assume you are asking what part of an element will always be the same, regardless of ionization or various isotopes. This would be the proton.
Do all isotopes of an elements have different numbers of electrons?
No. The essence of an isotope is that all isotopes have the same number of protons in the nucleus, and thus the same number of electrons. What varies is the number of neutrons in the nucleus.
How do isotopes of the same element have the same atomic size?
Isotopes of the same element have the same atomic size because atomic size is determined by the number of protons and this number is always constant for an element. The mass number of isotopes may however vary.
Is it true Different isotopes for the same element will always have the same numbers of neutrons?
Yes. it is true. Isotopes of the same element always have different number of neutrons.
How do scientist tell the different between two isotopes of the same element?
scientists Can tell the difference between two isotopes of the same element because, isotopes of the same elements always have the same number of protons.
In alpha and beta decay the parent elements is always a different element from the daughter element?
true
Do the nuclei of all atoms of a given element always have the same number of neutrons?
No - different isotopes of an element have different numbers of neutrons. All atoms of an element will have the same number of protons.
Why can 2 atoms of the same element have different numbers of neutrons but must always have the same number of protons?
They are called Isotopes
What do atoms of the same given element share?
Atoms of a given element always have the same number of protons in their nucleus. Neutrons can vary (in different isotopes) and electrons can vary (in different ions) but protons are always the same for a given element. If the number of protons is changed, then you no longer have the same element.
The mass of any two atoms of the same element is always the same?
The masses of any two atoms of the same element are not always the same. Atomic mass (the mass you see on the periodic table) is just a weighted average of all of the weights of all of the different isotopes of an element.
What is mass number of an isotope?
The mass number of an element is equal to the number of protons in the nucleus, and this always determines the element in the Periodic Table. Different isotopes of the same element have differing numbers of neutrons in the nucleus, but always the same number of protons.
What isotopes always have the same element?
Isotopes are variations of an element. Isotopes of one element always have the same number of protons because it's the number of protons that define the element. Isotopes of an element have the same number of electrons which will equal the number of protons. (That ignores atoms that are in the form of ions.) Different isotopes of the same element have different numbers of neutrons. The variations in the number of neutrons make the mass of atoms different but they do not change the element nor do they change the chemical properties of the element. Some isotopes of an element can be radio-active, that is, they are unstable and can emit an alpha or beta particle or a gamma ray. As an example, carbon has 6 protons and most atoms have 6 neutrons. A few carbon atoms have 8 neutrons with a mass of 14. It is known as "Carbon 14" and is radio active. That is because the nucleus can emit a beta particle and in doing so, the atom actually changes to a nitrogen atom.
Is calcuim a mixture?
Only of isotopes. Calcium is an element. No mixture of chemicals can ever be a single element. The atoms of any element, such as calcium, always have the same number of protons and the same number of electrons. The number of electrons in an atom is the same as the number of protons in that atom. Different Isotopes of an element have different numbers of neutrons in the nucleus, but this doesn't change any of the chemical properties.
Which is not true all isotopes of an element have the same number of electrons?
All neutral atoms of an element, including any of its isotopes, always do have the same number of electrons. The existence of isotopes has nothing to do with the number of electrons in an atom. Instead, the number of neutrons varies between isotopes of the same element. The number of electrons varies from that of a neutral atom only if an ion of the element is formed.
What is a plutonium?
A radioactive element with several isotopes that always has 94 protons within its nucleus.
